I think is ok. The design choice is that closed brackets are not allowed by 
themselves in math mode unless part of a \around environement. The standard 
way to create one is to type an open bracket (which then insert both open and 
closed parenthesis in the document within an \around environment) and then 
edit to obtain the required behaviour. If you want to type text freely you 
have to insert a text-mode box inside math, there you can then use again 
parenthesis freely, i.e the key ')' insert a ")" glyph.

Of course you can change the behaviour and bind the ')' key to the same 
command the '(' key is bound to, i.e. create an \around environment. But I 
haven't tried.
